SPECULUM FOR DILATING A BODY CAVITY

摘要

(~7) A speculum (700) for dilating a body cavity includes a base (706) and a number of arms (710) pivotably attached to the base (706). There is an actuator (708) movably attached to the base (706) for causing each of the arms (710) to move relative to each other from a closed position to an opened position so that a body cavity can be smoothly opened after the arms (710) have been inserted into the body cavity.
